TIE AND RAIL-CLABIP.

Specification of Letters Patent.

Patented Mar. 216, 1915.

Application filed December 2, 1914. Serial No. 875,066.

To all whom it may concern Be it known that 1, HUGE MGCONAUGHY, acitizen of the United States, and resident of Cleveland, in the countyof Cuyahoga and State of Ohio, have invented certain new and usefulImprovements in Ties and Rail- Clamps, of which I hereby declare thefollowing to be a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same.

The objects of the invention are to provide a metallic tie for the railsof a railway track and the invention also includes resilient means forclamping the rail securely to the tie in such a manner as to permit of aslight amount of yielding of the rail to lateral strains and pressure,such as occur when a train is rounding a curve, and in this manner toprevent injury. to the wheel flanges,

and the disagreeable shock occasioned to the passengers by the blow uponthe rails.

The invention comp ises the combination and arrangement of parts andconstruction of details, hereinafter described, shown in theaccompanying dra ings and specifically pointed out in the. claims.

in the accompanying drawings Figure 1 is a transverse section of therail showing the tie and clamping device; Fig. 2 is a transverse sectionof the tie showing a side elevation of the device; Fig. 3 is a viewshowing a modification of the wedge.

In these views the tie is shown to be channel shaped and is arovidecwith a vertical body portion A, and top and bottom flange members B andC respectively, extending laterally from the body portion.

l) is the rail which is firmly seated upon the tie. Upon each side 01"-the rail is a vertical opening a, a in the upper flange B. Through theseopenings are inserted the holding or clamping dogs E, E, which areprovided with the heads 6, c, which overlap the flanges a, d, or" therail on each side. The lower extremities or" the clamping dogs providedwith horizontally projecting extremities c, c, which are turned towardeach other. The resilient wedge H is inserted between the projectingextremities of the aforesaid clamping dogs and the lower face oil theupper flange and extends horizontally through the opening 0 in thevertical body of the tie. This wedge is peculiarly formed of springmetal and has two leaves spaced apart to give a limited amount ofresiliency thereto, and is secured by passing the reduced extremities h,it, through the opening 0, and turning them in reverse directions asshown in Fig. 2 to clench them upon the tie body. This spring is formedby folding a bar of steel and then tempering the body portion to hardenthe same.

In Fig. 3 a modified form of wedge is shown in which the larger end ofthe wedge is open, and the reduced extremity is secured in the opening 0by means of a split pin P.

in use a certain amount of resiliency is obtained by means of the railresting upon the verhanging flange of the tie. In addition resiliencyagainst lateral pressure upon the rail is obtained by means of thespring wedge, which permits the rail to yield slightly under pressuresulliciently to relieve the shock of a swiftly moving train, withoutpermitting of the slightest relaxing of the grip of the clamping dogsupon the flange of the rail, since the wedge is driven tightly throughbetween the dogs and tie to insure a constant grippin action of thedogs. As the wedge bears down upon the projecting extremities of thedogs, their heads are brought more forcibly into engagement with saidrail flanges, and if any spreading action takes place the dogs willfulcrum upon the walls of the openings in the upper flange at L, thusincreasing the pressure propor tional to the relative position of thefulcrum points to the extremities of the clamping dogs.

Having described the invention what I claim as new and desire to secureby Letters Patent is:

1. In combination with a metal tie having an overhanging flange, of arail transversely seated thereon, and a resilient securing means forsaid rail comprising a clamping dog upon each side of said rail, eachdog passing through an opening in said flange, and on ch dog having ashoulder adj aoent to its inner extremi y, each dog having a headengaging said rail, and a wedge shaped spring interm diate between saidshoulders on said dog and the lower surface of said flange upon saidmetal tie.

2. In combination, a metal tie having a horizontal member and a verticalmember, a flanged rail mounted upon said horizontal member, saidhorizontal member having an opening on each side of said rail, aclamping dog passing through each opening and having a head engagingsaid flanged rail, said dogs also provided With reversely eX- tendingshoulders in their inner ends, and a Wedge shaped spring seated on saidshoulders, and engaging said horizontal flanged member, and means forholding said Wedge shaped spring.

3. In combination, a metal tie having a vertical member and anoverhanging horizontal member, a rail seated thereon, a pair of clampingdogs engaging the opposite sides of said rail and passing looselythrough said horizontal member, the lower edges of said clamping dogsprovided with shoulders, and a two leafed spring, one leaf engaging saidhorizontal flange and the other said shoulders in said dogs, said springpassing through said vertical member, and means for securing said springin place.

In testimony whereof, I hereunto set my hand this 16th day of November,1914:.
